Course detail

Fluid Structure Interactions

FSI-MZHAcad. year: 2018/2019

This subject is a continuation of the subject Fluid Engineering. The aim is deepening the knowledge abot unsteady motion of stiff and elastic bodies in real fluid. Intention is application on design of hydraulic elements and systems.

Learning outcomes of the course unit
